In the title binuclear centrosymmetric complex, [Cu(2)I(2)(C(8)H(6)N(4))(C(18)H(15)P)(2)]·2C(3)H(7)NO, the bis-bidentate 2,2'-bipyrimidine ligand bridges two copper(I) ions, each additionally bound to an iodide anion and a triphenyl-phosphane ligand in a distorted tetra-hedral N(2)IP geometry. The complex mol-ecules pack in columns parallel to [100] generating cavities occupied by dimethyl-form...

The title complex, [Zn(2)(C(12)H(6)O(4))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)]·4H(2)O, is a binuclear complex with two independent Zn(II) ions in a slightly disorted trigonal bipyramidal environment, coordinated by one aqua ligand, two naphthalene-1,8-dicarboxyl-ate ligands and one 2,2'-bipyridine ligand. π-π Inter-actions [centroid-centroid distance of 3.8489 (5) Å] and O-H⋯O hydrogen bonds connect ...

The first base-stabilized iodoborylene platinum complex was prepared through the addition of 4-picoline (4-Pic) to a suspension of an iodo-bridged binuclear iodoboryl complex. An X-ray structure determination of the title compound has characterized the molecular structure as cis-[Pt{BI(4Pic)}I2(PCy3)]. The bond lengths lie in the expected range for neutral, base-stabilized borylene complexes. T...

The complete binuclear complex in [Fe2(C7H4NO4)4(OH)2]·2H2O, is generated by the application twofold symmetry. The Fe(III) atom is coordinated by the O atoms of two bridging hydroxyl groups and by two N and two O atoms from two pyridine-2,5-di-carboxyl-ato ligands, forming a distorted octa-hedral geometry. The Fe⋯Fe separation within the dinuclear complex is 3.0657 (4) Å. In the crystal, O-H⋯O ...

Reaction of [(Me3tacn)V(CF3SO3)3] (Me3tacn = N,N',N''-trimethyl-1,4,7-triazacyclononane) with LiCN in DMF results in oligomerization of cyanide to form [(Me3tacn)2V2(CN)4(mu-C4N4)]. The structure of this binuclear complex features a planar tetracyanide unit bridging two VIV centers via imido type linkages. The conjugated pathway provided by the bridging ligand leads to strong antiferromagnetic ...

The title complex, [Ni(2)(C(4)H(8)N(4)O(2))(6)](NO(3))(4)·2CH(4)O, contains a centrosymmetric binuclear nickel(II) complex bridged by a pair of 4-amino-3,5-bis-(hydroxy-meth-yl)-1,2,4-triazole ligands. The separation between the Ni(II) atoms is 3.962 (1) Å. The Ni atoms are in a slightly distorted octa-hedral coordination. Inter-molecular N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds connect the ligand...

In the binuclear title compound, [Mo(2)(C(12)H(15)N(4)O(2))(2)Cl(2)O(3)]·H(2)O, the complex mol-ecules have approximate C(2) symmetry. Both Mo(V) atoms have a distorted octa-hedral coordination environment with cis-positioned terminal chloride and oxide groups. The heteroscorpionate organic ligand binds to the Mo(V) atom via an N(2)O donor set. The water mol-ecule bridges two complex mol-ecules...

The formation of water chains in cytochrome c oxidase (CcO) is studied by molecular dynamics (MD). Focus is on water chains in the K channel that can supply a proton to the binuclear center (the heme a3 Fe/CuB region), the site of O2 reduction. By assessing the presence of chains of any length on a short time scale (0.1 ps), a view of the kinds of chains and their persistence is obtained. Chain...

A new complex [Dy(C5H7O2)3(C5H5NO)]2·2CHCl3 (1) has been synthesized by the reaction of pyridine-N-oxide with dysprosium (III) acetylacetonate in an n-heptane/chloroform mixture (1/20). X-ray data show that each atom is chelate-like coordinated three ligands and oxygen from two bridging molecules pyridine-N-oxide, which unite atoms into a binuclear complex. Static (constant current) dynamic (al...
